MediaTek Launches Dimensity CX C10 Max for Googlebook

MediaTek has introduced the Dimensity CX C10 Max, the first processor in its new Dimensity Compute Experiences family for personal computers. The company says the 3nm SoC is intended for an upcoming premium, ultra-portable Googlebook rather than the lower-cost Chromebook segment where MediaTek has traditionally been more visible.

The chip combines an eight-core Arm CPU, an 11-core Arm Immortalis-G925 MC11 GPU and MediaTek’s NPU 890, rated at up to 55 TOPS of dense AI performance. MediaTek is positioning that NPU around on-device Gemini Intelligence and agentic-AI workloads, but the TOPS figure is an accelerator throughput rating, not a general measure of laptop performance.

The most useful context is MediaTek’s own Kompanio Ultra 910. The earlier Chromebook processor uses the same one Cortex-X925, three Cortex-X4 and four Cortex-A720 CPU layout, the same 12MB L3 and 10MB system-level cache totals, the same Immortalis-G925 MC11 GPU and the same NPU 890 family. This makes the CX C10 Max look like an evolution of an existing high-end Arm laptop platform rather than an entirely new CPU architecture.

There are measurable specification changes. MediaTek lists the CX C10 Max’s Cortex-X925 at up to 3.73GHz versus 3.62GHz for Kompanio Ultra 910, raises supported LPDDR5X data rate from 8533Mbps to 9600Mbps, and rates the NPU at up to 55 TOPS versus up to 50 TOPS. Those changes can improve specific workloads, but they do not establish a corresponding percentage gain in application or gaming performance without independent testing in finished systems.

MediaTek specifies UFS 4.0 storage for the CX C10 Max. That is a different platform choice from the PCIe NVMe SSDs common in premium Windows laptops and can affect upgradeability and OEM system design. The SoC also supports LPDDR5X rather than user-replaceable DIMMs, reinforcing that this platform is aimed at tightly integrated thin-and-light systems rather than modular notebooks.

For displays, the SoC can drive an internal panel at up to 4K60 and as many as two external 4K displays through DisplayPort Multi-Stream Transport. Its media engine supports 4K60 10-bit decoding for AV1, HEVC, AVC and VP9, which matters for efficient high-resolution streaming without leaning entirely on the CPU or GPU shader cores.

Google’s first announced Googlebook systems span Intel Core Ultra Series 3 and Qualcomm Snapdragon X Elite processors. MediaTek’s CX C10 Max adds another Arm option and, more importantly, establishes a dedicated MediaTek computing brand above its existing Kompanio Chromebook line.

That gives Googlebook OEMs another route to thin, highly integrated Arm hardware, but buyers should wait for the actual device configuration before comparing it with Intel- or Qualcomm-powered models. Battery capacity, cooling, memory capacity, storage implementation and software compatibility can matter as much as the SoC specification sheet. MediaTek has confirmed the silicon; real product positioning and comparative performance remain open questions.
